When asked how many people are using Google+ Dodge replied, "Any numbers you've heard are way low."

"How many then?" We asked.

"I've heard 1.5 billion," joked Heiferman.

Dodge just smiled and replied, "The numbers are way low."

Goldstein brought up a good point though. "You're Google," he said. "You put a bar across the entire platform with a bright red box, or worse a big blue arrow, that encourages you to sign up, and it's not that hard to get to 50 million users."
